Does granite have layers?
As granite is an igneous material, it would have to undergo a melt, taking away any form it has, such as cleavage. However, in a granite dike, the outer layer of the granite will be a chilled margin, giving it a glassy outer layer.
When gneiss is formed... quartz... feldspar... mica... and other minerals of granite are rearranged into alternation WHAT?
Bands.
Is gneiss nonfoliated?
No. Gneiss has foliation in the form of alternating light and dark bands.
What is the difference between conglomerate and gneiss?
Conglomerate is a clastic sedimentary rock that has rounded pebbles included among its clasts. Gneiss is a high-grade foliate metamorphic rock characterized by alternating light and dark bands. It forms from the metamorphism of granite or schist.
Which feature would easily distinguish schist and gneiss from quartzite and marble?
schist and gneiss arefoliated and in gneiss you can see the bands.
Which rock has a granite look with bands?
Gneiss

Three examples of igneous rock?
foliated rocks, defined as "metamorphic rocks with parralel layers or "bands". three examples of these foliated rocks are gneiss, slate, and schist. three examples of foliated rocks are schist, gneiss, and schist.
What is the description of foliated?
A rock with minerals aligned into bands or layers.
Is gneiss nonbanded?
No. Gneiss has alternating light and dark bands.
What is the streak color gneiss?
Bearing in mind that Gneiss is not a mineral, and that it is very hard, Gneiss does not leave a streak, but scratches the plate (don't try it - this is not how you classify Gneiss). Gneiss is classified by its Gneissose Banding - distinct bands of light Feldspar/Quartz and dark Micas. It is also classified by the extent of metamorphism which has taken place.
Is gneiss nonfoliated?
No. Gneiss has foliation in the form of alternating light and dark bands.

What type of rock has distinct bands?
Folliated Metamorphic Rock. Example is Gneiss (Banded Gneiss)
How is gneiss rock formed?
Gneiss is formed from pre-existing rocks that are subjected to intense directional pressure and heat, causing an alignment of their constituent minerals into parallel bands, a texture that is referred to as foliation.
